Veilweaver Harridan

Warp (If this creature would leave the battlefield, instead shuffle it into owner's library. Reveal the top card of that player's library. If it is a permanent, put it onto the battlefield.)
"Every faction accused the witches for their own reasons. Most of them were wrong, but the erratic nature of the Veil's spontaneous disgorging caused no end of strife." --Shon's Guide to the Realm
